Overview

The Svetlana 6L6 Medium tubes have the classic Sylvania STR sound.
Soft, medium, and hard style descriptions refer to break up modes of the tube for an overdriven guitar signal. Soft-rated tubes break up easier and have the least headroom, yielding a heavier, harder distortion. In comparison, hard-rated tubes must be driven harder to yield a distortion which typically ends up being thinner and warmer sounding distortion, while medium-rated tubes fall in between.

I finally bought these tubes after years of using EL34s. I decided to go with the Red/Soft Svetlana tubes because not only are they Russian, but they are the least expensive duet I can find anywhere! When they arrived, I could immediately feel the tube responding to my playing. It has a very nice, tight clean and a wonderful, smooth breakup. For the price, I thought I may be compromising quality, but it has so far surpassed my expectations. I haven't had the tubes for more than 10 days, so I can't comment on how long they will last. I expect it to last as long as the 34s I took out, but regardless, I'll be buying the same tube again when the time comes.

I purchased two pair of Svetlana Duet tubes, one medium/green and one hard/blue. Note that these are sold as Duets, not matched pairs, because they most certainly were not matched. One tube of the medium duet was basically dead. The hard duet had bias currents that differed by over 15%. I swapped tube positions and the current moved with the tubes, so it isn't the amp. I had to use the remaining medium with one of the hard ones to get a pair matched within 10%. Unmatched tubes with a 25% failure rate turn out to be very expensive.

      Comments about Svetlana 6L6 Tube:

      I bought these for a 70's model B15N Ampeg amp.
      I had used other Russian 5881s and they worked well.
      I was completely delighted after installing these
      Svetlana green 6L6's. They Sounded very warm and gave the
      overall bass a tighter and clearer tone. I believe that these tubes are well matched and will work great for this amp. I would recommend these for any bass amp using 6L6 tubes ie Bassman, Ampeg.

      Nice

      Comments about Svetlana 6L6 Tube:

      I've always used NOS tubes in my vintage amps. My Revered Hellhound is a newer amp and the circut does not respond like I thought it would with NOS tubes. I replaced the original Sovteks(because they were getting tierd) with a duet of Svetlana red/soft 6L6GC. Very impressed! Now it sounds like it did when new. Shipping was fast. I may have to order another set as spares.

      Sounds pretty good so far

      By Andrew Meyer

      from Oak Lawn, IL

      Comments about Svetlana 6L6 Tube:

      I got a set of the red/soft biased tubes for my Egnater Tweaker 40. They sounded kind of flabby on the low end at first, but after a few days of break in that mostly went away. Did some tweaking and now the flabbiness is pretty much gone. Once I got past this they were definitely an improvement over the stock Ruby tubes. They've added a lot more harmonic character to the amp, which is most prominent on the "hot" setting. I didn't like the "hot" setting before; I used to just drive the hell out of the "clean" setting, which sounded amazing but was way too loud. Now I'm getting pretty close to the same sound at lower volumes on the "hot" setting. They seem solidly built, they've been in the amp for about a month now and I haven't had any problems. They're also shorter than the stock Ruby tubes, which makes regular maintenance a lot easier (used to have to remove the tubes to get the chassis out of the enclosure).

      Great tube

      By Solerso68

      from Maryland

      Comments about Svetlana 6L6 Tube:

      A great low priced alternative to the SED "winged C" 6L6GC. While. both this tube and the SED are the only modern tubes that approximate the sound and performance of the great RCA and Sylvania "tall bottle" 6L6GC tubes, they come close enough to be effective, desirable replacements.IMHO there were only 2 6L6GC's, the aforementioned tall bottles and the little round, clear top GE egg with the side getters. The Tungsol 6L6GC-STR is a good copy of that particular tube. These svetlana 6L6GC tubes are recommended.

      Comments about Svetlana 6L6 Tube:

      i love um
      i went from groove tubes to these and i have never been happier they cleaned my mushy bottem end up and are more crisp than groove tubes i bought the soft quad all were matched perfectly great sounding tubes for blues,rock,and even metal
      we dropped one of them on a concrete floor and it didnt bust nor did it go microphonic
      for the price on the soft quad its not a bad price could be a little cheaper thou

      excellent!

      from Chicago

      Comments about Svetlana 6L6 Tube:

      I would not count on these "duets" being matched. I bought a batch of 5 singles and popped them in and out of my amp with a dual bias tester until I found two that measured exactly. It was worth the trouble because they sound great. The glass is heavy, they are well made tubes with no noise and apparently good vacuum. I can bias them on the high side and they sound great, especially for the price.

      Svetlana 6L6GC Tubes

      By WesTehNinja

      from Texas

      Comments about Svetlana 6L6 Tube:

      My tubes were also not matched very well. The current was off by at least 10% and it made my amp sound really muddy. My advice is to steer clear of these tubes. My previous tubes were hard breakup, and I got a medium set of these, and I get more breakup in my clean channel than with my previous tubes. These are definitely not a buy.

      Great Tone!!

      By VH1984

      from New Hampshire

      Comments about Svetlana 6L6 Tube:

      I have been using these tubes for about (2) years now in my Marshall JCM900 Amps. I usually buy a bunch of duets & rematch them in my Maxi-Matcher Digital Tube Tester - That way I can get them 1-2MA apart. These tubes last a long time when biased correctly - I ordered the medium/green duets & tightly match them into quads - they are very clean & clear with good breakup but still stay warm & dynamic - they also have tight vacuum with solid construction. They are a very underated tube - They are also a good alternative to standard Sovtek 6L6 Power Tubes - Great Value & Great Tone - Highly Recommended!!
